19-0859; Rev 0; 8/07 KIT ATION EVALU E L B AVAILA 2MHz to 1.6GHz 45dB RF-Detecting Controllers and RF Detector General Description Features o Complete RF-Detecting PA Controllers (MAX9930/MAX9931/MAX9932) o Complete RF Detector (MAX9933) o Variety of Input Ranges MAX9930/MAX9933: -58dBV to -13dBV (-45dBm to 0dBm for 50Ω Termination) MAX9931: -48dBV to -3dBV (-35dBm to +10dBm for 50Ω Termination) MAX9932: -43dBV to +2dBV (-30dBm to +15dBm for 50Ω Termination) o 2MHz to 1.6GHz Frequency Range o Temperature Stable Linear-in-dB Response o Fast Response: 70ns 10dB Step o 10mA Output Sourcing Capability o Low Power: 17mW at 3V (typ) o 13µA (typ) Shutdown Current o Available in a Small 8-Pin µMAX Package MAX9930–MAX9933 The MAX9930–MAX9933 low-cost, low-power logarithmic amplifiers are designed to control RF power amplifiers (PA) and transimpedance amplifiers (TIA), and to detect RF power levels. These devices are designed to operate in the 2MHz to 1.6GHz frequency range. A typical dynamic range of 45dB makes this family of logarithmic amplifiers useful in a variety of wireless and GPON www.DataSheet4U.com fiber video applications such as transmitter power measurement, and RSSI for terminal devices. Logarithmic amplifiers provide much wider measurement range and superior accuracy to controllers based on diode detectors. Excellent temperature stability is achieved over the full operating range of -40°C to +85°C. The choice of three different input voltage ranges eliminates the ne...
